Title: Heating unit for vehicles
Inventor: REINHARDT RUDOLF
IPC: F24H9/14
Filed: 1984-12-21
Abstract: A heating unit for vehicles, in particular a vehicle auxiliary heating unit having a sealing arrangement between a chamber through which a heating medium such as air or water flows and an exhaust gas chamber is further developed in such a manner that, even if this sealing arrangement starts to leak, no combustion gases can pass into the passenger compartment in order to take account of the safety requirements of the users. According to the invention, in the region of the flange connection at which the sealing arrangement is arranged between the two housing parts, an intermediate space is therefore designed and is in contact with a chamber of the heating unit which is under vacuum so that combustion gases can collect in this intermediate space if the sealing arrangement starts to leak and these gases can then be extracted together so that they do not pass into the passenger compartment. This chamber of the heating unit which is under vacuum can be formed, for example, by the intake side of a combustion air fan or by a chamber around the sparking plug.

Title: Speed-measuring device for rail vehicles
Inventor: KIELGAS HANS DIPL ING
IPC: G01P3/50
Filed: 1985-07-27
Abstract: The invention relates to a speed-measuring device for rail vehicles, measurement being independent of the skidding/slipping or sliding of one or more wheel sets of the vehicle. The speed is to be measured with high accuracy in conjunction with the large installed powers or torques of present-day rail vehicles. An accurate measured value is generated independently of the skidding/slipping or sliding of one or more wheel sets by feeding a single-phase or multiphase AC voltage or alternating current of fixed or variable frequency in a "stator" of a linear-motion machine which is connected to the vehicle, the rail representing the "squirrel-cage rotor" of the linear-motion machine, and the electromagnetic interaction between the stator of the linear-motion machine and the squirrel-cage rotor being evaluated for the purpose of determining the speed of the vehicle. In the range of low speeds down to stoppage, one winding phase of the linear-motion machine is fed with AC voltage of constant frequency amplitude, and the voltage induced in the second winding phase, which is offset spatially by 90 DEG  with respect to the first, is rectified in correct phase relation with the feed voltage, the rectified voltage of the vehicle speed being linear. For higher operating speeds of the rail vehicle, the linear-motion machine is fed with two-phase or multiphase three-phase voltage or two-phase or multiphase three-phase current of variable frequency and ...

Title: Signal transmission device
Inventor: KIERSCHKE KLAUS DIPL ING
IPC: H01R35/02
Filed: 1985-10-24
Abstract: Until now, sliprings, point contacts or the like have been used for transmitting electrical voltage signals from a stationary part to a rotating part. If the rotating part (rotor) has to move through only a limited rotation angle, as is frequently normal in the case of actuating drives, the signals can also be transmitted using a flat ribbon cable 3. This is attached to the stationary part (stator) 1 and to the rotor 2 and runs in a groove 4 in the stator having one or more turns. In order that the flat ribbon cable 3 is guided in an improved manner, it is laid in a loop 5 and, in addition, a guide part 6 is provided which can move in a rotating manner. This guide part 6 is moved by the loop 5 and effectively prevents the flat ribbon cable becoming jammed or winding up in an undefined manner. <IMAGE>

Title: Regenerative machine and heat engine with external heat supply
Inventor: EDER FRANZ-XAVER PROF DR ING
IPC: F02G1/055
Filed: 1986-03-06
Abstract: The invention relates to regenerative working and thermal processes, the drive energy of which is supplied by external combustion of the fuel. The heat supply for this, almost always assumed to be isothermic, is achieved only in exceptional cases, since the flue gases usually have a low specific thermal capacity. The invention explains new types of processes in order to obtain the optimum thermodynamic efficiency even for these less efficient heating cases. The heating heat exchangers and thermal regenerators used in regenerative processes are replaced by regenerative heat exchangers, which comprise a plurality of short regenerators, which are connected by tubular heat exchangers for the heating medium. It is thereby possible to supply the heat to the process not at a fixed but at a sliding temperature. In the same way, regenerative coolers are used for the dissipation of heat from Stirling engines and regenerative heat pumps or refrigeration machines, if, for example, only air is available as heat transfer medium. <IMAGE>

Title: Method and device for contactlessly measuring the resistivity of semiconductor wafers
Inventor: KATAGIRI KIYOO
IPC: G01R27/02
Filed: 1986-07-30
Abstract: The device according to the invention has a pair of exciter and sensor coils (4, 5), facing one another, for inducing an eddy current in a semiconductor wafer (W) inserted therebetween and, respectively, for sensing this eddy current by means of the electromagnetic induction. In contrast to conventional devices of the same type, each of the coils (4, 5) is formed with a core (4b; 5b) of a particular design which has a cylindrical cup-like shape with a central projection on the bottom so that an E-shaped axial cross-section is obtained, the turns of the wires (4c; 5c) of the associated coil (4, 5) being wound around the central projection. This special design of the cores (4b; 5b) in combination with use of a radio frequency of 0.2 to 5.0 Mhz for the excitation provides the advantage that the leakage loss of the magnetic flux can be effectively minimised so that the accuracy of the measurement of the resistivity of the semiconductor wafer (W) is considerably increased without providing an electrostatic screening plate which is indispensable in the known devices. <IMAGE>
